For connecting the fence connector push down the red button and push the stripped cable into the connector. Ensure the
connection by pulling the wire lightly. Install the earthing wire to the black connector in the same way and secure the
connection.
In WZG 1000 you can connect the return voltage control to the green connector and earthing testing to the blue connector
in the same way.
If you can't install the connection wire directly to the energiser, please use WZG earth cable to connect the fence to the
device. WZG earth cable has a thick insulation that isolates the high voltage that the fence energiser produces. You can
use this cable to take the fence wire through a wall and you can also install it underground if this is necessary.
Please never use any low voltage cables or ordinary electrical installation cables as these can not to completely isolate
the high voltage pulse that has a voltage of up to 10 000 volts. Any leakages diminish the effect of the energiser and may
cause disturbances in telephones, TV-picture or radio.
5. Earthing
Earthing refers to fence earthing in use. When an animal touches the fence conductor and the ground at the same time it
completes the electric circuit and suffers a shock. Therefore a proper earthing is necessary for the function of the fence.
Earthing can be done either by using the ground as the electric earth or by using a separate earth wire in the fence. In
traditional earthing the animals gets a shock when it touches the fence wire and the ground at the same time. In the two
wire system the animal gets a shock when it touches the electric wire and the ground wire at the same time.
5.1 Traditional earthing by using the ground and earthing electrodes:
The fence conductors are the wires suspended on the insulated posts and the earthing conductor is the ground. Connect
the earthing terminal of the fence energiser to the ground via earthing rods driven into the ground. The best place for
earthing rods (electrodes) is a damp place near to the fence. The high power WZG electric fence energisers require at
least three earthing rods. Two earthing rods are recommended for the smaller WZG 100 and 300 models. Additional
earthing rods may be needed in dry conditions or when building long fences. The earthing rods must be connected to the
energiser with a wire that has a minimum diameter of 1 mm. Fix the connector wire to the earthing rods firmly with screws.
For the best result please use original WZG earthing rods and wires.
Never use any fixed structures such as pipelines or buildings for earthing a fence energiser.
Inadequate earthing is the most common cause to poor function of the fence and disturbances in radio devices or
telephones.
5.2 Two wire system
This system gives the best result in conditions where the ground has poor electric conductivity. This can be the case in
very dry conditions and on snowy ground.
Use two fence wires that are placed 10 cm from each other. The upper one is the "live" wire, connect it to the fence
energiser. The lower wire is the "earth" wire; connect it to the earthing terminal of the energiser. The animal gets a shock
when it touches there two wires at the same time. However, we recommend connecting the earth wire also to the ground
with an earthing rod to minimise radio disturbances and to ensure the functionality of the fence.
6. Disturbances in electrical devices
The radio frequency of the pulse of a fence energiser is so low that a correctly installed electric fence does not cause any
visible or audible disturbances in radio devices. The main reason for disturbances (typically a snapping noise in
loudspeakers) is an inadequate or incorrectly implemented earthing of the fence. Check and fix the earthing of the fence
according to the chapter 4 in this guide.
The other typical reason for disturbances is sparking. A spark spreads a wire spectrum electromagnetic radiation that can
be heard as snapping in loudspeakers of as horizontal disturbance stripes in TV picture.
Visible sparks on fence wires are signs of poor connections. They cause disturbances and add resistance to the fence
thus reducing its effect. Always use proper connectors when connecting the energiser to the fence or connecting wires to
each other.
7. Thunder protection
WZG energisers are protected against over voltage and the WZG warranty covers also thunder damage. However, it is
not possible to build the fence energiser to withstand all possible situations. Therefore it is wise to use an WZG lighting
diverter whenever the fence is situated in very open ground or if thunder occurs frequently in the region. It is also
advisable to disconnect both the fence and mains power from the energiser if you leave your electric fence unused for
any longer time.
8. Indicator lamp
In WZG 100, 300 and 600 the indicator lamp is on all the time when the energizer is connected to power source and shuts
down during the pulse approximately 45...55 time per minute depending on the model.
